I would say the real problem is USB itself. |

What is USB after all? It's a way of sticking any old random thing into |
16 |
a socket and getting the computer to magically do stuff. So if the |
17 |
system software then goes ahead and does stuff, it's only really |
18 |
operating as designed and as spec'ed right? |

Yes, those 40 holes are probably all true and quite possibly all |
21 |
exploitable, and they should also be fixed. But the real problem is that |
22 |
USB even exists at all. |

btw, when you say "Isn't Linux supposed to be more secure than this??" |
25 |
the answer is a resounding NO |

The Linux=safe, Windows=notsafe delusion comes from the 90s when Windows |
28 |
had no real security features at all, or even any realistic ways to |
29 |
limit and control access. Linux had a Unix-style userland and kernel, so |
30 |
you automatically got multi-user/multi-process with per-user |
31 |
permissions. That alone, by itself, is probably the largest single |
32 |
security advance in all of computing history. Everything else is icing. |

There is nothing in Unix really that is "secure by design", and all von |
35 |
Neumann machines are actually insecure by design |
